Introduction
Etiology
(risk factors)
Epidemiology
- more common in males
- antibiotic-resistant strain of Klebsiella pneumoniae infected 19 people (7 deaths directly attributable to Klebsiella) at the NIH Clinical Center in Bethesda, Maryland Aug 2011-Sept 2012
Pathology
- community acquired lobar pneumonia
- virulent, necrotizing pneumonia with lung abscesses & empyema
- dependent lobes are affected more frequently
Clinical manifestations
Laboratory
Radiology
- chest X-ray may show bulging fissure(s)
Complications
- carbapenem-resistant Klebsiella pneumoniae (CRKP) & other similarly resistant Enterobacteriaceae are resistant to most antimicrobial drugs, & are frequently fatal[4]
- carbapenem-resistance (India, Pakistan) conferred by New Delhi metallo-beta-lactamase 1 (emergence in 2010)
Management
- 3rd generation cephalosporin plus aminoglycoside
- carbapenem for extended spectum beta-lactamase producing Klebsiella pneumoniae
Comparative biology
- colistin-resistance in carbapenem-resistant Klebsiella pneumoniae identified in a mouse model[7]
- in 3xTg-AD mice, Klebsiella pneumoniae can translocate from the gut to the bloodstream by penetrating the gut epithelial barrier & susequently infiltrate the brain by penetrating the blood-brain barrier[9]
